A Mesoscale Convective System (MCS) with a large or several clusters of storms will move across the northern half of the state from late this morning through early evening. In addition, a few severe storms could develop ahead of the MCS. Very heavy rainfall, damaging wind gusts and hail are the main threats. Within the Enhanced Risk area, the potential exists for swaths of wind damage as well as a couple of tornadoes.
After this MCS either dissipates or moves into Georgia, another MCS with a line of storms is forecast to enter the northern portions of Alabama after 10 pm and once again affect mainly the northern half of the state before dissipating by 8 am Sunday somewhere near or north of a Livingston – Montgomery – Auburn line. Although not as potent as the first round, very heavy rain with localized flooding and a few damaging wind gusts are possible.
A boundary will be left in place near or south of the Livingston – Montgomery – Auburn line, and scattered thunderstorms are forecast to develop Sunday afternoon into the evening hours south of this line. A couple of damaging wind gusts will be possible across the southern half, but widespread severe weather is not expected.
On Monday, yet another MCS will affect portions of the state during the afternoon and evening hours with very heavy rainfall, a few damaging wind gusts and hail. Total rainfall from today through early Monday will be widespread 1-3 inches with some locations potentially receiving double these amounts.
The unsettled pattern continues from Tuesday into Friday with scattered to numerous showers and thunderstorms each day mainly during the afternoon and evening hours. The overall severe weather chances look very low with heavy rainfall and flooding being the main threat each day.
